LACING-TIP.

Specification of Letters Patent.

Application filed March 6, 1909.

Patented Aug. 24., 1909.

seriaiNo. 431,652.

To all 'whom it in ay concern.:

Be it known that I, FERDINAND THUN, a citizen of the United States, residing in Wyomissing, near Reading, in the county ol' Berks and State of Pennsylvania, have invented certain new and useful im. rovements in Tracing-Tips, of which the iol owing is a specification.

My invention relates to shoe and corset. lacings and particularly to those provided with sheet-metal stiffeners forming covering-tips on the fabric. These sheet-metal tips are interrolled with the end portions of the lacing fabric so as to form either a straight or tapered covering, and are adapted to grip the incloscd fabric so as to permanently secure them thereto.

The object of my invention is to provide a fabric-covering stifener having distinguishing lettering; and to adapt such lettering to serve as a gripping means for iirmljr securing the stiiener to the fabric, and provide a preliminary roll in the letter impressed portion of the blank, whereby the symmetrical formation of the nished tip will be facilitated and the stifi'ening eti'eot of the metal covering increased.

The invention is fully described in connection with the accompanying drawing and is speciiicall)T pointed out in the claims.

Figure l shows a finished lacing tip embodying my invention. Fig. 2 shows the finished stifliening blank ready to be interrolled With an end portion of the lacing fabric to form the finished lacing tip. Fig 3 is a cross-section on the line 3-3 of Fig. l; and Figs. 4 and 5 are similar cross-sections indicating letter impressions of modified character.

The stieniug blank A for forming the lacing tip is stamped from suitable sheet-metal or equivalent material; the size of the blank as shown being adapted to roperlvxT inclose the interrolled end portion ci the lacing fabric in tapering cylindrical form. By means of suitable dies provided in the stamping press, letter-impressions e are formed in the sheet-metal blank. These impressions, as indicated, consist ot' a series of letters arranged in a line extending' lengthwise of the finished tip so as to forma distinguishing naine; the successive letters being gradually reduced in height toward the smaller end ol" the finished tip as shown. The letter-impressing dies are so formed as to simultaneously impart to the letter-impressed portion of' the blank, as indicated in Fig. 2, alateral curvature corresponding with the desired roll of the finished tip, thereby positively giving practically the finished form to such portion of the blank, indcpernlentli-v of the subscuent rolling-'up operation of the blank with t 1e fabric, so as to greatlyv facilitate such operation and avoid distortion of the stamped impressions; while at the same time the strength and rigiditbY of the tip is greatly increased by the impressing and curving ci the blank. The letter-impressions are adapted, as indicated, to serve the further purpose oi gripping the fabric (Z so as to permanenti)T secure thereto the interrolled covering-tip, the fabric being pressed into engagement therewith in the rolling-up operation. As shown the metal depressed by the letterforming dies is cut so as to provide a more positive gripping action, While at the same time permitting the fabric to show through the metal covering and thereby accentuate the exposed lettering.

Additional gripping means, as pnnctures b or edge-teeth c, may be provi( ed on the blank il desired, but such means are preferably not exposed in the finished tip as are the letter-im ressions.

lnsteac oi pressing the instal inward in forming the letter impressions, as shown in Fig. 3, the letter-metal may be pressed outward, as indicated in Fig. 4, the fabric d being pressed outnfard into such depressions to engage the saine; or the vmetal may be cut away as indicated in Fig. 5, the fabric d being naturally ressed into engagement with the openings tlius formed in the metal.

What l claim is 1. A tipping blank for lacings stamped from sheet-metal and lorincd with letter-impressions adapted to grip the interrollcd lacing fabric.

2. A tipping blank 'for lacings stamped 'from sheet-metal and formed with letter-impressions, tlie letter-impressed portion of the blank being curved to conform with the roll of the applied tip.

3. A taperingtip blank for lacings stamped from sheet-metal and formed with a series of letter-nupressions ci' decreasing Width and adapted to grip the interrolled lacing fabric.

4. A tapering -tip blank for lacings stamped from sheet-metal and formed with a series oi letter-impressions of decreasing Width, the letter-impressed portion ol' the blank being curved to conform with the tapering roll of the applied tip.

5. A lacing having a covering-tip lormcrl l'rorn a sheet-metal blank having letter' iinpressionsJ said blank being interrolled with the lacing fabric and gripping the latter by means of said letter impressions.

6. A lacing having a tapered covering-tip `formed 'from a sheet-metal blank provided with a series of letter impressions of decreasing Width, said blank being interrolled with the lacing fabric and gripping the latter by means of said letter' impressions.

7. A lacing havinl a tapered covering-tip formed from a sheet-metal blank having a series of letter impressions ol decreasing Width, the letter-impressed portion of said blank being curved to coliform with the tapei-ing roll of the finished tip7 and the blank interrolled with the lacing fabric.

8. A lacing having a coverinwtip formed from a shectanetal blank provilecl with letter-impressions and additional lfabric-gripping rncans, said blank being interrolled with the lacing fabric so as to expose the letterimpressions only.

ln testimony whereof, I aflix my sign ature, in the presence of two Witnesses.
